Apesar de lo roto y defectuoso ni siquiera prendió el mouse definitivamente vender este tipo de cosas es nefasto.

I have used the Kensington Expert Mouse for 25 years. I love the ergonomics and longevity. I have one that I use daily since 2005, and it still works great.So, wireless? I was skeptical. No longer! This thing is seamless and smooth. I’ve only had it a month, but I look forward to years of reliability.

I have not purchased this actual device. i bought the Kensingston Expert Mouse Pro back in the 90s for $120 (A LOT at the time for a trackball). It FINALLY died after about 12 years. I contacted Kensington because I wanted to buy another one just like it. The rep said, 'its lifetime warranty. Whats your address, we'll send you another one." No kidding. They sent me a brand new one. And that replacement one is still working some 10 years later still. I feel kinda bad, but later, i took the old one apart and was able to clean it really well and now they both work.Although I only use one (Sorry, Kens, I thought it was dead). But, if you clean them, they perform better.However, now, i need a wireless one, so that's right, im going with Kensington, and this 'mouse' looks very much like the ones I own. Respect for and thanks to Kensington.

I have several of these trackballs. This one is a new HW rev. I notice two differences:1) There is a timeout and a sleep mode on this rev. I hope this improves battery life (the older rev is a battery eater)2) The case molding is a little different. It feels the same except that ion this version, the scroll wheel catches frequently, very annoying (thus 4 stars). I believe the cause is in the spacers between the buttons. I took some 200 grit paper and rounded all the edges and so far the scroll wheel is smooth.3) the button click is still crisp but a little softer.I am trying NiCads in this version, so far so good. The old version doesn't work well with NiCads.

The trackball, itself, is fine. However, the renewed version did not come with the USB nano dongle, which means that I have to connect to my PC via bluetooth. I just wish that I knew ahead of time that I wouldn't get on, because I would have just bought it new instead of renewed. The bluetooth can be finicky at times, but it works overall.

I have used trackballs for awhile as I find them easier on my arthritic hands. This large ball and platform allows my hand to not have to bend much at all and is super easy to use. the butttons are large and reachable with little to no movement. The software allows you to program various buttons and button combos - I have my password saved to one button, saving tons of time when I can just click once instead of typing a 16 character password. The bluetooth occassionally gets a little slow if I have a lot of other devices near causing interference, but it resets easily. My laptop is usually about 10ft away from my keyboard/mouse area and 98% of the time it works flawlessly. Worth the minor occassional inconvenience for a very comfortable and efficient mouse.

Love this trackball. I use the wired one at work but wanted something more clean looking at home. It works great and has pretty good battery life. Easy to bring with me on the go.

It is a good mouse. Works as expected. Bluetooth choppy in Linux, proprietary dongle is acceptable work-around.
